Haproxy provides high availability, Load Balancing and proxies based on TCP and HTTP applications that support Virtual Host , it is a free, fast and reliable solution. Haproxy is especially useful for Web sites that are heavily loaded, and often require session-hold or seven-tier processing. Experiment (I.)Experimental purpose: Using Haproxy to do load balancing clusters (layer seven)Lab Environment Prepara

.4) Seven-layer load Balancing (HTTP)Depending on the virtual URL or IP, the host name receives the request and then turns to the appropriate processing server).The most common four-and seven-layer load balancing in our operations is the emphasis on these two load balancers. 1) Four-tier load balancing is based on ip+

1. network load balancing working principle Network Load Balancing uses a cluster of two or more host computers working together to provide high availability and scalability for servers. An Internet client uses an IP address or a group of addresses to access the cluster. Clients cannot distinguish clusters from single servers. Server ApplicationsProgramIt does not indicate that they are running on the clus
